There is one of them on the route I frequent and I was also laughing that It even clocked me. Motors all bursting passed it was dhowing "41" "39" and It suddenly popped up with "11" i near shat myself and fell of my bike laughing, I have never noticed those things picking me up before.
Put in 32 miles today, It was pissing of rain and was out with mate. good times. My mate is fit as f**k though and I was blowing oot ma arse at the few wee hills at the end.
